In the last few weeks the smart money decided that legacy SaaS is dead. Riding the wave of Claude Code, Anthropic hard launched several new tools that took direct shots at software companies serving niche industries and there was lots of selling. The general wisdom is that SaaS profits will be eaten by agents, and that this will happen soon.
I have a different view.

- The software business isn’t about the quality of the software or how well the platform solves problems. These things matter, but like any other company, having skilled operators doing the blocking and tackling of “good business” is what ultimately drives periods of significant momentum and long term growth.
- Successful SaaS companies don’t just minimize customer churn, they turn their customers into champions and evangelists. They build entire communities, host conferences, and work to make their end users part of a tribe. Relationships are a strategic asset, and a team of high-performing CSMs can leverage their customer relationships to drive momentum.
- Switching costs are real. It’s painful to change enterprise systems, and at many enterprises it is a process in the worst possible interpretation of that word. In 2014 I was part of a team tasked to find a new enterprise CRM and EMS to replace a legacy vendor. I left that organization in 2018 with this work well underway, and I recently saw that in 2026 that the new system is finally, fully live.
- Agents have significant, society altering potential. But many of the use cases and solutions aren’t unique. We’re seeing the early signs of commoditization. SaaS companies can leverage their distribution and roll agents and models directly into their platforms. They already have the relationships to glean customer insights, and the workflows in place to turn those learnings into AI-enhanced product features.
- SaaS companies are not going to be caught off guard here. Just listen to any business or tech adjacent podcast and you’ll hear a steady stream of ads for AI-enabled SaaS products. These companies have long seen the future and are making the necessary product moves to retain customers.
This is the moat (and there’s plenty I didn’t mention).
LLMs and agents will have a significant impact on the SaaS business, but I think it’s much more likely that they’ll find themselves as part of an existing ecosystem vs. replacing it outright.
